Technical Specifications

This conduit reducer features 4" NPT female threads on the large end transitioning to 3" NPT male threads on the reduced end, with overall dimensions of 4.5" length x 4.5" depth x 1.56" width and weighing 2.48 pounds. The Feraloy iron alloy construction provides superior mechanical properties compared to standard steel, while maintaining full compatibility with rigid steel conduit and IMC systems. The fitting is specifically rated for Class I, Division 1 hazardous locations and complies with NEC/CEC standards for classified area installations.

Installation Process

1. Verify conduit system is de-energized and properly locked out/tagged out per safety procedures
2. Cut and thread 4" rigid or IMC conduit to proper length using standard NPT threading equipment
3. Apply appropriate thread compound rated for hazardous locations to male conduit threads
4. Thread 4" conduit into large end of reducer, ensuring full thread engagement for explosion-proof seal
5. Install 3" conduit section to small end of reducer with proper thread compound application
6. Verify all connections are tight and properly sealed per manufacturer specifications and local codes

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
• Oil and Gas Operations - Drilling platforms, pump stations, and distribution facilities
• Paint and Coating Operations - Spray booths, mixing rooms, and solvent storage areas
• Grain Handling Facilities - Elevators, mills, and processing equipment installations
• Aircraft Hangars - Maintenance areas and fuel handling systems
• Marine Applications - Ship electrical systems and offshore platform installations
• Pharmaceutical Manufacturing - Clean rooms and solvent processing areas
• Industrial Motor Control Centers - Large equipment connections requiring conduit size transitions

Conduit Reducer System Benefits

Conduit reducers eliminate the need for complex conduit bending or multiple fittings when transitioning between different conduit sizes in a raceway system. This direct size transition approach reduces installation time, minimizes potential leak points, and maintains the integrity of the explosion-proof conduit system. The reducer design also allows for more efficient use of available space in crowded electrical installations while maintaining full code compliance.

Why Choose Feraloy Iron Alloy?

Feraloy iron alloy represents advanced metallurgical engineering specifically developed for demanding electrical applications. This proprietary alloy composition provides superior tensile strength, enhanced corrosion resistance, and improved dimensional stability compared to standard malleable iron or steel fittings. The result is a conduit reducer that maintains explosion-proof integrity even under extreme temperature variations, chemical exposure, and mechanical stress - making it the preferred choice for critical hazardous location installations where failure is not an option.
